Clearing things up . Hydrophobic polymers that undergo complex formation with β‐cyclodextrin in aqueous solution display reversible thermosensitive solubility. Supramolecular effects lead to a new kind of LCST behavior (LCST=lower critical solution temperature), which is evident from clouding and clearing points at defined temperatures (see picture). The polymer was synthesized by free‐radical polymerization of the complexed monomer in water.
